Luminescence in collision-induced dissociation of ND3 by H+, H2+, and H3+ beams at energies below 1000 eV

The luminescence of ND radical and hydrogen Balmer series has been observed in the collisions of Hn+ (n = 1, 2, 3) ions with ND3. Absolute luminescence cross sections, excitation functions, as well as electronic ND(c-a)/ND(A-X) and Dβ/Hβ branching ratios were determined. The rotational and vibrational temperatures characterizing populations of the ND∗(A3Π,c1Π) states were estimated from computer simulations of the spectra.
